hi, all I want to known if where is some progress in this forking bug. I met this problem too because of proxy forking, and i got a SDP from 183 response , then a SDP in 200 OK finally response was received, i have to use the SDP in the finally response but sofia-sip stack does not give it to me
If there is already a fix, please give me a hint , thanks Regards, 2008-02-22 Liang 发件人： Pekka Pessi 发送时间： 2008-01-11 22:20:27 收件人： Bernhard Suttner 抄送： sofia-sip-devel@lists.sourceforge.net 主题： Re: [Sofia-sip-devel] Different To-Tags in Session Progress 183 and200 OK 2007/12/21, Bernhard Suttner <[EMAIL PROTECTED] >: > Yeah, without 100rel it does work without a problem.

I'll try to get some time for fixing the forking, I think Misha also needs the fix... --Pekka > Am Freitag, den 21.12.2007, 15:06 +0200 schrieb Pekka Pessi: > > 2007/12/14, Bernhard Suttner <[EMAIL PROTECTED] >: > > > I try to do my best and look after this bug.
